The gear pinion I9is fast on a transverse. shaft22 suitablyjournaled at its rear endvin the drum I "and extending forwardly'outoffltli casing section 5 through afront'opening 23in said sectionandin'which said shaftlisalso journal'ed.

A conventional form of lock 26 is provided in the outer end of the shaft22 for operation by a key 21 insertable in a keyhole 28 in said end ofthe shaft, said lock being of a suitable form to engage a pair of keeperlugs 23 extending forwardly from the hub I2 upon opposite sides of theshaft 22 in the rear of the hand crank 24.

Opposite sides 38, SI of the opening 20 provide stops for engaging thegear pinion 19 to limit rotation of the gear wheel IS in oppositedirections when the wheel fastening members M are fully retracted andprojected.

As will now be seen, operation of the described gear train by the handcrank 24 to rotate'the gear wheel l in one direction, i. e.counterclockwise as viewed in Figure 5, into its limit of movement inthat direction will retractthe wheel fastening members l4 into the gearcasing section 5 so that the wheel 2 is unfastened, or unlocked, forremoval off the gear casing 3. Upon replacement of the wheel 2, androtation thereof to register the openings l l with the openings H), thegear train may be operated by the hand crank 24 to rotate the gear wheelIS in the opposite direction, 1. e. clockwise as viewed in Figure 4,whereupon the wheel fastening members 14 will be projected into theregistering openings III, II to fasten the hub l2, and hence the wheel2, to said gear casing 3.

Any suitable form of dust cover, not shown, for applying to the wheel 2to cover the described fastening means may be provided if desired.

The foregoing will, it is believed, sufiice to impart a clearunderstanding of my invention, without further explanation.

Manifestly, the invention, as described, is susceptible of modification,without departing from the inventive concept, and right is hereinreserved to such modifications as fall within the scope of the appendedclaims.

Having described the invention, what is claimed as new is:

1. Fastening means for securing an automobile wheel 'to a brake drumhaving a spindle, said means comprising a concentric annular frontcasing on said drum having circumferential openings thereon, a dishedannular hub on said wheel fitting over said casing and havingcircumferential openings therein registering with the first namedopenings, a circular series of elongated longitudinally arcuatefastening members in said casing for projection and retraction s endwiseinto and out of the registering openings to fasten said hub to saidcasing and unfasten the same, means in said casing supporting andguiding said members for projecting and retracting movement endwiselongitudinally in an arcuate path and including a wheel rotatable onsaid spindle in driving and supporting engagement with said members andoperative in opposite directions to project and retract said members,manually operative means for rotating the second named wheel, andlocking means for disabling said last named means at will.

2. Fastening means for securing an automobile wheel to a brake drumhaving a spindle, said means comprising a concentric annular frontcasing on said drum having circumferential openings thereon, a dishedannular hub on said wheel fitting over said casing and havingcircumferential openings therein registering with the first namedopenings, a circular series of elongated longitudinally arcuatefastening members in said casing for projection and retraction endwiseinto and out of the registering openings to fasten said hub to saidcasing and unfasten the same, means in said casing supporting andguiding said members for projecting and retracting movement endwiselongitudinally in an arcuate path and including guides for said membersand a wheel rotatable on said spindle in driving and supportingengagement with said members and operative in opposite directions toproject and retract said members, and manually operative means forrotating the second named wheel.

3. Fastening means according to claim 2, wherein said manually operativemeans comprises a toothed sector in an opening in the second named wheeland a shaft journaled in said drum and casing and having a driving gearpinion therein for the second named wheel working in said opening andmeshing with said sector.

4. Fastening means according to claim 2, wherein said manually operativemeans comprises a toothed sector in an opening in the second namedwheel, and a driving gear pinion in said casing working in said openingand meshing with said sector, said opening having sides engaging saidpinion to limit rotation of the second named wheel in oppositedirections when said members are fully projected and retracted.

5. Fastening means for securing an automobile wheel to a brake drumhaving a spindle, said means comprising a concentric annular frontcasing on said drum having circumferential openings therein, a dishedannular hub on said wheel fitting over said casing and havingcircumferential openings therein registering with the first namedopenings, a circular series of elongated longitudinally arcuate fastenermem-- bers in said casing for projection and retraction endwise into andout of the registering openings to fasten said hub member to said casingand unfasten the same, means in said casing supporting and guiding saidmembers for projectingand retracting movement endwise in an arcuate pathand including guides for said members and a wheel rotatable on saidspindle in driving and supporting engagement with said members andoperative in opposite directions to project and retract said members,and manually operative means for rotating the second named wheel, saidfirst named means further including a transversely grooved stud on saiddrum for each arcuate member confining the member in the groove thereofbetween the stud and the second named wheel for sliding and rotarymovement endwise" in said groove.
